Abstract

The present invention comprises a device which allows to introduce a substance from a chamber A, having a pressure P1, into a chamber B, having a pressure P2 higher than P1, said device comprising a stator, in which the pressure is that of the chamber B and in which rotates a rotor formed by a chamber V at the pressure P1, said rotor comprising a central opening through which is introduced the product coming from the chamber A, and a peripheral slot adapted to be opened, under the thrust produced by the material collected in the rotor chamber V and subjected to centrifugal force, in order to let said material run through the slot, into the stator.
